Marty,

Yes, the spindles are the same, arms are not. Easy to tell if tie rod is rear or front. I heard there are two sets of front axles in PHX somewhere, might be a place called 'Desert Mountain' yard that has some stockpiled. Wanted $500. Each. OK price. If a non P, might be worth getting if all there for decent price. I found a place in BC that I got my rear steer arms from, knew what I was talking about, Eh. Not need axle, just everything else. I got power steering box from something else, but if included, good deal. Had to shorten drag link, made
LH die to cut threads. I got tie rod from 1960's truck, just need correct taper to fit arms.

Keep eyes out for 10 on 8.750", tubeless (22.5") wheels. Can be redrilled to 10 on 7.25" bolt pattern with shop made adapter sleeve. See my px on earlier text, two different white wheels.
